LATEX MODIFIED CONCRETE BRIDGE DECK OVERLAYS

Preventative Bridge Deck Maintenance, 8 Locations

This 8 bridge project in Monroe County, NY is located in the Towns of Chili, Gates, Henrietta, Irondequoit, and the City of Rochester. The aggressive schedule requirements of this project are noteworthy, and the improvements were comprised of a variety of tasks including hydrodemolition, latex modified concrete deck overlays, armorless bridge joint systems, complete fascia []

Why Latex Modified Concrete Is Used For Cold Climate Bridge Deck Overlays Updated November 2019 In colder climates, bridge decks undergo a freeze-thaw cycle more severe than other types of concrete infrastructure. This is because they're exposed to weather conditions on the top and bottom, unlike sidewalks and other concrete flatwork.

Evaluations of Latex Modified Concrete Overlay Bonded to

Latex modified concrete (LMC) overlays are placed over normal concrete substrates to increase the life of bridge decks. However, the property mismatch between these two concrete types gives rise to interfacial stresses that cause premature delaminations, corner lifting, and cracking.

Latex Modified Concrete (LMC) is typically used for shallow overlays, deck patching or substructure patching of bridge rehabilitation projects. LMC may be hand mixed using the mixture proportions provided in table 703-1 in the Standard Specifications for Construction ; however LMC is typically produced in mobile latex trucks which are

Design and performance of low shrinkage UHPC for thin

1. Introduction. Bridge deck deterioration can involve cracking of the concrete deck and corrosion of reinforcement. Bonded overlay is used to rehabilitate concrete bridge decks given its ability to seal cracks, reduce the rate of corrosion of reinforcement, and provide a smooth riding surface [].Successful application of thin bonded overlay necessitates that the overlay material develops low

Latex-Modified Concrete Overlays Using Recycled Waste

Polymer-modified concrete is typically used in bridge deck overlays due to its superior tensile strength and low permeability. Polymer modification of concrete is performed by incorporating an appropriate dose of polymer during the mixing process, which adds to the cost of concrete. In this study, the use of waste latex paint to produce an

Hydro-Demolition | Hydro-Technologies

Latex Modified Concrete Overlays are excellent structural repairs for bridge decks. The service life of the bridge deck can be extended by 25 years because the existing concrete deck facilities are preserved by the “low porosity characteristics” of the Latex Modified Concrete.
